Kia Forte shaking and loss of power at 40-50 MPH with check engine light on Kia Forte

Some Kia Forte owners report experiencing shaking and loss of power specifically at speeds of 40-50 MPH, accompanied by an illuminated check engine light. These issues may indicate underlying problems within the engine or emissions control system, which should be addressed promptly. Many owners find that checking for Diagnostic Trouble Codes (DTCs) can help pinpoint the specific issue causing the check engine light to activate. Symptoms such as noticeable car shaking and a flashing check engine light are often linked to engine misfires, which can result in rough idle, decreased power, and poor fuel economy. Additionally, some owners report that a pinched exhaust pipe can lead to a jerking sensation or loss of power. Problems with engine timing, particularly if the crank and cam sensors are out of sync, may also contribute to these performance issues. It is recommended that owners inspect the exhaust system for obstructions and address any detected misfires by consulting a qualified mechanic if the issues persist.
